Arrange the following compounds in order of increasing boiling point
l.CH 3CH2CH2OH
II.CH 3CH 2OH
III.CH3CH2CH2CH2OH
IV. CH3CH 2CH2CH 2CH 3
I < II < IV < III
IV < III < II < I
I < II < III < IV
IV < I < II< III
Correct answer is D
| Ethanol | 78°C |
| Propanol | 97°C |
| Butanol | 118°C |
| Pentane | 36.1°C |
Hence, the arrangement is IV, I, II, III.
